The glory of God is the beauty of His spirit which emanates from His character, from all that He is. The glory of God is eternal, and will never fade or pass away. The glory of God is revealed in His creation and is constant:
The heavens are telling of the glory of God and their expanse is declaring the work of His hands; day to day pours forth speech, and night to night reveals knowledge (Psalm 19:1).
The glory of God is revealed in His Son, Jesus Christ, who is the most amazing gift that God has given. Jesus declared,
No one is good—except God alone (Luke 18:19).
God is good in that He has a plan to redeem fallen mankind. The salvation Jesus provides attests to His goodness and love: “but God shows his love for us in that while we were still sinners, Christ died for us” (Romans 5:8).
Goodness is part of God’s nature, and He cannot contradict His nature. Holiness and righteousness are part of God’s nature; He cannot do anything that is unholy or unrighteous. God is the standard of all that is good. The fact that God is good means that He has no evil in Him, His intentions and motivations are always good, He always does what is right, and the outcome of His plan is always good. There is nothing unpleasant, evil, or dark in Him. The Bible teaches that God’s goodness extends from His nature to everything that He does (Psalm 119:68).
“The LORD is good and His love endures forever; His faithfulness continues through all generations” (Psalm 100:5).
On the basis of Scripture, it is clear that the glory of God embraces the goodness of God. The glory of God also embraces His holiness and righteousness – they are also part of God’s nature. While goodness, holiness and righteousness are part of God’s unchanging nature, those facets combine to make up the whole, which manifests in the glory of God.
Are they the same? No, but God's goodness is one facet of His glory.
